CONSTRUCTION OF VESSELS.

SPECIFICATION forming part of Letters Patent No. 681,962, dated September 3, 1901.

Application filed February 16, 1901. Serial No. 47,556. (No model.)

T0 00% whom it may concern:

Be it known that I, ERAST E. GOULAEFF, a subject of the Czar of Russia, residing at St. Petersburg, Russia, have invented certain new and useful Improvements in the Construction of Vessels, of which the following is a specification.

This invention relates to improvements in ships hulls; and the object of the invention is to provide a hull suitable for merchant vessels and ships of war by which excessive rolling of the vessels is overcome, and in the case of war vessels the dangers due to near explosion of torpedoes or mines or from ramming by another vessel are minimized. For this purpose the invention consists of a ships hull comprising a portion above water-line and a portion below water-line, said lower portion projecting laterally beyond the upper portion and the projecting part of said lower portion being composed of a plurality of closed water-tight compartments.

In the accompanying drawings, Figure 1 represents a transverse midships section of a ships hull embodying my invention; and Fig. 2 is a section on line 2 2, Fig. 1.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A indicates that portion of the hull above the water-line, and B the portion below the water-line. The portion B is of greater width than the portion A, and the projecting part a of the same is oc copied by a plurality of 'olosed water-tight compartments or cells I). These cells are included within the shell of the hull, and in the case of Warships the armor-belt extends outside of the same, so that they are totally inclosed within the hull. Said projecting portion a preferably gradually diminishes in width from the middle toward each end of the hull, as clearly shown in Fig. 2. The cells or compartments b are preferably arranged in two or more layers, three being shown in Fig. 2.

The advantages of my improved construction of hull are that when applied to passenger-boats excessive rolling motion is eliminated, thereby increasing the comfort of the passengers. When applied to Warships it provides a gun-platform of great stability. The ship is protected from the effects of mine explosions by the water-tight compartments, as they prevent the ship from filling. Foundering of a ship when the same is torpedoed, rammed, or run into is prevented by means of the water-tight compartments running the length of the ships sides. The compartments offer protection to the engines and boilers and magazines of a warship against projectiles. I

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A ships hull, consisting of a portion above water-line and a portion below waterline, said lower portion projecting laterally beyond the upper portion, and the projecting part of said lower portion being composed of a plurality of closed water-tight compartments, substantially as set forth.

2. A ships hull, consisting of a portion above water-line and a portion below Waterline, said lower portion projecting laterally beyond the upper portion, and the projecting part of said lowerportion decreasing in width gradually from the middle toward each end of the hull and being composed of a plurality of closed water-tight compartments, substantially as set forth.

3. A ships hull, consisting of a portion above water-line and a portion below waterline, said lower portion projecting laterally beyond the upper portion, and the projecting part of said lower portion decreasing in width gradually from the middle toward each end of the hull and being composed of a plurality of closed water-tight compartments arranged in a plurality of layers, substantially as set' A forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing Witnesses.

E. E. GOULAEFF.
